    The increase in the molar conductivity of\[C{{H}_{3}}COOH\] with dilution is due to

    A)  increase in degree of ionization

    B)  decrease in interionic forces

    C)  intermolecular forces increases

    D)  No degree of ionization

    E)  None of the above

    Correct Answer: A

    Solution :

                    According to Ostwalds law with the dilution, the degree of ionisation of weak electrolyte increases. Thus, the molar conductivity will be increase with dilution due to the increase in number of ions.
